where do you ride? i don't think i would want to ride something that small and soft outside of the park if there is any kind of elevation, i weigh 200lb and my smallest board is a 158 mid stiff. I know mr. david blog man rides some pretty small boards though and is heavier than you so to each his own.
summit county. My main all mountain board is a NS Heritage X in 158 and I have no problems with it. Weight limit on the 155 wide artifact says it's up to 200lb. What I'm really curious is if the artifact will be too soft for ANYTHING outside of the park, and vice versa if the garage will not be soft enough for what I want and be too similar to my heritage. I wish I could check the boards out in person but unfortunately I can't and I haven't really found any in depth reviews that address this.
